Villa boss O'Neill unsure of Guzan readiness

The American goalkeeper is joining Villa from Chivas USA, subject to a UK work permit.

Asked if he thought Guzan was ready to step into Scott Carson's shoes, O'Neill said: "That is a difficult question. He is dead keen to come. Only time will tell if he is good enough now, but he is up for the challenge just as he was a few months ago. And he is every bit as keen this time around."
